Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block in the preparation of heterocyclic compounds due to its active methylene group, which readily undergoes condensation and alkylation reactions. Commonly employed in the synthesis of dyes, fragrances, and functional materials where controlled ester hydrolysis or decarboxylation is required. Its stability and reactivity make it valuable in multi-step synthetic routes, especially in the development of active ingredients in crop protection agents and medicinal compounds.
